How does the Audi A5's quattro all-wheel drive system enhance handling and stability?

I am considering purchasing an Audi A5, but I am not sure if the quattro all-wheel drive system is worth the extra cost. Can someone explain how this system works and how it affects the driving experience?

The quattro all-wheel drive system in the Audi A5 uses sensors to constantly monitor road conditions, distributing power to the wheels that have the most traction. This results in improved handling and stability, especially in adverse weather conditions.

I have been driving an Audi with the quattro system for years and highly recommend it. It also helps with cornering and provides better control when taking sharp turns.

I've found the quattro all-wheel drive system particularly beneficial when driving on hilly or mountainous roads. It helps with keeping the car stable and preventing skidding or slipping.
